Description
Technical field
The present invention relates to poly- based on reciprocal relation in wireless charging technical field, especially complicated multipath propagation environment
Burnt formula wireless charging technology.
Background technology
There are many electronic equipments (such as various kinds of sensors or wireless network node) of type due to planting in advance in actual life
Enter human body (including fixed such as pacemaker and dynamic such as capsule endoscopic), or is erected at unpowered condition or nothing
It in the complex environment that method is reached, or even is covered by vegetation environmental around and can not determine its accurate installation site, or because of peace
The crypticity of dress requires manually replace battery etc., is both needed to periodically or continuously carry out wireless charging.And in wireless charging technology
In, it is ensured that battery to be charged can effectively receive electromagnetic energy, and the radio wave that wireless charging device is emitted is to be charged
Battery region must have enough intensity.But if wireless charging device emits non-focusing radio wave, and there will be very big
Partial electromagnetic wave energy becomes ineffective radiation, energy dissipation is not only resulted in, also to people there is no being received by battery to be charged
Body and ambient enviroment cause electromagnetic pollution.Therefore, the target that wireless charging technology is pursued is the radio of charging equipment transmitting
Realize that good electromagnetic power focuses in region of the wave near charging equipment.

2. battery to be charged is difficult to find and be difficult to precise positioning, lead to the difficulty for determining focal zone in real time.Very much
In wireless charging application, the position of battery to be charged is difficult to discovery and precise positioning, even irregular variation, therefore
It can not just determine electromagnetic focusing region.For example, concealed installation, implanted installation, the installation of camouflage formula, underground, underwater, underground peace
Dress is blocked by vegetation, continuous device on the move, etc..
Review existing wireless charging technology, including near-field coupling charging technique and electromagnetic propagation charging technique or root
This does not consider electromagnetic focusing or attempts to focus based on preset simplified propagation model, does not have actuality and practicability；More
Accurate electromagnetic focusing can not possibly be realized when not grasping battery accurate location to be charged and current non-homogeneous propagation conditions still.
As the Typical Representative of the prior art, Ada S.Y.Poon are published in《IEEE- Circuits and Systems》Magazine " is used for
